BREAKING ROLLER.

Application filed September 20, 19%.

lhis invention relates to the rollers or cylinders used in so-called mutton-breakcrsamchInes having a nmnber o'l" rotateifl rol in i ipheral contaci with which a talna tr :ted is extended in a bend around each oi such rollers and in which, as the Fabric is advanced through the ma chine. bnttons or projections on the pe ripherics ot the rollers act to flex the labrie and hence to render more su giple the fibres thereof and to soften the same. hese rollers have heretofore been t'ornnwl. by driring into the wooden body oi the roller devices like miholstery tacks having mushroom shaped hollow heads or caps and slender shanks; the buttons formed by these devices work loose and tall out and their mietimes break oil and in time their :ear away and break oil, the detached. lJllljlOllS or broken-cit heads or the projectingstubs ct the shanks doing soi'netimes serious damage to the fabric. and sometimes, it the buttons are not. fully driven in or they work out, crevices are left between the surface of the roller body and the button heads in which stray threads of the fabric catch, so that the tabric becomes damaged also in this way.

The present invention contemplates the provisicm of a studded roller :lor use, for example, in a button breaking machine which shall not be subject to any of these faults and the cost oil which shall not be eXcessive.

In the d rawingi Fig. 1 is a transwerse sectional View of the improved roller; and

Fig. 2 is a similar sectional view of a fragment thereof on a larger scale, a part appearing broken away.

l is a cylindrical core composed at some suitably yielding material, such as wood; it is here shown as formed in sections, but that is not material. 2 a shell which is fitted over this core. It is preferably formed of some relatively min-yielding substance, as a hard metal. The parts 1. and 2 form the body of the improved studded roller. I aim to support each stud or button against lateral displacement in the wood of the core as an incident of the wrenching action exerted thereon when in use and which is one cause of the button: loosening and their shanks breaking on. tha is ti o principal reason for tittin and SGCLIILDO thereto a shell of t) e t3 0 relatively non-yielding mate nil as a hard Serial No. 138,?15.

metah which serves as a support for the s uds as will appear. The shell is bored with holes 3. y

The studs to a ll'ord the buttons are driven through the holes into the wood of the core, being leit projecting. (As a matter of actual practice holds to receive the studs, somewhat in ifliaineter than the studs, are previously formed in the core, which is usually of hard wood.) Each stud [its the holes 3 through which it .is driven, so that whereas it might otherwise be displaced latorally in the wood ot the core it i tally supported against such displacement by the relatively non-yielding material of the shell.

in the mannple illustrated the studs have heads in the form of enlargements thereon. Unc object of this is to provide them with acting or projecting portions of ample size without having their entering portions of excessive diameter. 5 designates the shank of a stud and (3 its head, which is mainly rounded or convex but cylindrical at its base portion 6. It the studs are thus provided with such heads the holes 3 are enlarged or counterbored as at 4t, so that When the studs are driven in their heads may stand countersunk in the shell 2 all around, one object of which is to sheath any latorally open crevice that would exist between any button head and the surface of the roller and in which threzds oil the fabric being treated might catch.

To anchor the studs in the roller I prefer: ably form the shank 5 of each as a series ol' truncated cones 5t having their major di ameters adjoining the head of the stud thus to term clinching shoulders 53; this is true except: with respect to the topmost cone, between which and the head (5 a cylindrical neck portion 5 is preferably left; of a size to tit snugly the holeeor bore 3.

i l herein; the studs are tirinly anchored in the wood against outward radial displace- .ment by the radially outwardly lacing shoulders it they are i'ornu-al with enlarged projecting n'irtions or heads they will obtain as to such heads a solid seat on the hard non-yielding shell against inward radial Lll:].)l2ll (:,li'lQll'll. The hard non-yielding shell. also determime: zu-curately the extent to which the studs may be driven in and it the stud heads are all termed ol the same height the assembling oi: the studs with the roller can be eti'ected so that they will all form uni:tormly-high projections.

Usually the-heads Will not be. in-ushrooin.--

shaped or; coneavo-convex, as heretofore, butt solid, as shown at the left in Fig. Thus wearing away of anyhead leaves it always Without the formation of an edge or burr to catch in or cut the fabric and it cannot by Wear become detached bodily from the shank.

The heads are not only countersunk but fit snugly the counterbores l, so that the hard non-yieldingshell acts to support the heads themselves against lateral distortion. Since their base portions 6 do not conform-to the general shape of'theheads, but are cylindriealand of greater depth than the eounterbores- (inotherwords, since the holes have i snug--fit around the studs at the perlphery otthe shell) no recesses exist to collect'dyestu if-"or othen foreign matter Which would soil ordn-jure the fabrics, and since the shell is non-yield-ingthey-cannot be formed by any-lateral pressing action of-the studs.
